Tools
evermint_mint (API key required)
Mint a tamper-evident, cryptographically timestamped record of an action.
evermint_mint({
agent_id: "billing-agent-1",
action_type: "decision_made",
payload: { decision: "approved", confidence: 0.97 }
})
evermint_verify (public)
Verify a single record by Record ID.
evermint_verify({ record_id: "EVR-12C5N1A2" })
evermint_list_records (API key required)
List records for the authenticated org with optional filters. Returns metadata only (no payloads).
evermint_list_records({
agent_id: "billing-agent-1",
action_type: "decision_made",
since: "2026-01-01T00:00:00Z",
until: "2026-05-01T00:00:00Z",
limit: 50
})
All filters are optional. limit defaults to 50 (max 200).
evermint_get_record (API key required)
Fetch the full contents of a single record, including its original payload. Returns 403 if the record exists but belongs to a different organization.
evermint_get_record({ record_id: "EVR-12C5N1A2" })
evermint_verify_chain (public)
Verify a sequence of hash-chained records. Confirms each hash matches its content, and each chain_link correctly references the prior record.
// Explicit list, oldest first
evermint_verify_chain({
record_ids: ["EVR-AAAAAAAA", "EVR-BBBBBBBB", "EVR-CCCCCCCC"]
})
// Or walk forward from a starting point
evermint_verify_chain({
start_record_id: "EVR-AAAAAAAA",
length: 10
})
Returns per-record hash_valid, chain_link_valid, plus an overall chain_intact: true|false.
